Water purifier products have become a necessity for every household.Every household will choose to install a household water purifier product when decorating a new house or customizing the whole house.As we all know,the core accessory of a water purifier product is the water purifier filter element.So does everyone know the replacement cycle and maintenance method of the filter element?In fact,many people are wandering in the misunderstanding,but they don't know that if the filter element is not used correctly,it is a waste of resources and a waste of life!
The impact of filter expiration
1.The filtering effect is weakened and affects health
The first reaction to the expiration of the filter element is blockage.The blocked filter element will reduce the water flow and the filtering effect,resulting in a decrease in the "purity" of the purified water.Not only that,the filter element will also absorb a large amount of organic matter,which can easily become a breeding ground for bacteria. If the filter element is overdue,the drinking water will be polluted.If you drink it straight at this time,it will absorb some harmful impurities into the body,causing harm to the body.
2.Overworked waste of money
The water purifier is basically filtered step by step.For example,the front filter element - PP cotton is blocked, and the large particles of impurities such as sediment and rust in the water will follow the raw water directly into the second filter element,so that it is not responsible for filtering large particles. The impurity second-stage filter element has to undertake this extra work,and overloading it will shorten its service life very quickly.Originally,during this period of time,only the replacement cost of the "PP cotton filter element" was borne,but because of the bad habit of not "regularly replacing the filter element",it was necessary to bear the double-layer cost of two filter elements,or even more.If the filter element is not replaced for a long time,the operation of the water purifier will also become sluggish, which will reduce the life of the water purifier and increase the cost!
How can I tell if the filter is expired?
So how do we know that the filter element should be replaced? If it is replaced early,it feels wasteful, and if it is replaced later, it will affect the water quality.No one wants to use a water purifier of several thousand yuan, and the water to drink is still not safe water, right? Buying a water purifier is not for comfort.It's about helping us protect the health of our families.
Generally,the service life of the filter element:
pp cotton filter: 3-12 months;
pre-activated carbon filter: 3-12 months;
ultrafiltration membrane filter: 3-12 months;
RO membrane: 12-36 months;
Post activated carbon filter: 12-24 months.
But that's just a vague conceptual standard.The water quality varies from place to place,and the frequency of use of the water purifier is different.For example,within the validity period of the filter element,the whole family traveled to the door for a period of time.During this period of time,the filter element was not used,so is this period of time also counted as the service life? These are It's hard to judge.
Teach you several ways to judge when to replace the filter element
1.The effluent flow becomes very small (indicating that the filter element is blocked, and the filter element should be cleaned to restore the normal flow).After cleaning, the flow rate is still very small,which cannot meet the needs at this time.
2.The taste of the effluent decreases, and the taste is close to that of tap water, that is,the chlorine smell of tap water cannot be removed,indicating that the activated carbon filter element has been saturated with adsorption and the activated carbon is ineffective.
3.The filter element has not been replaced for a year.
